Rifle is 50 cal, barrel marked Douglas XX, swamped. Rifle weighs just over 9 pounds. If you guys like it , I will build another and offer it for sale. I would up to 54 or 58 caliber. Here in CO, they have upped the requirement to 54 for round ball elk hunting. I seem to recall that the last elk I shot with this complained about the small wound channel. All joking aside, our shots are usually within 30 yards. Sometimes within 30 feet. My hunting partner swears that a cow elk came up and kissed him this past September. Of course, he had a bull tag! How about this same form, as a smoothie 20 bore?
